However this debate about the Pope’s speech goes, one thing is certain. A lot of people are going to quote passages from the Koran and a lot of people are going to pick up a copy in English and take a look. Good.

The trick, though, is to know which Koran you’re looking at. There’s a lot of differences between translations, especially those funded by the Saudis. Khaleel Mohammad, a professor in California, did an excellent overview of who funds which versions, where they diverge, and what their biases are, here.
